P305: Physics and our World (4 lectures per week)

Preamble to the course

This is a course that assumes no quantitative background and is meant as an introduction to a

physicists’ way of understanding the world we inhabit. It is a survey of the hierarchical

structuring of the universe in categories of space, time, matter and energy, from the very small

to the gigantic. Rather than providing a simplified treatment of the subjects and categories by

which the physicists seeks to understand the physical universe the course seeks to take the

participant on a path that provides a glimpse of the process by which this understanding is

sought.

Question paper pattern for CBCS scheme

THEORY QUESTION PAPER PATTERN

Each hard core theory paper (4 credit course) examination is for 70 marks.

Each soft core (2 credit course) theory paper examination is for 70 marks.

Open elective (4 credit course) theory paper examination is for 70 marks.

Question paper pattern for hard core 70 marks theory paper:

Each hard core theory paper syllabus is divided into 4 units. The semester ending examination

will be aimed at testing the student’s proficiency and understanding in every unit of the

syllabus. The blue print for the question paper pattern is as follows:

Each question paper will consists of 3 sections: A B and C.

Part A: Six questions of 5 marks each out of which four to be answered (4 x 5 =20 marks).

Short answer conceptual/reasoning questions shall be asked in this section to test conceptual

understanding of the student.

Part B: Six questions of 10 marks each, out of which four to be answered (4 x 10 = 40

marks). Descriptive/derivation questions shall be asked in this section.

Part C: Three problems (or questions on conceptual extensions) of 5 marks each, out of

which two to be answered. (2 x 5 = 10 marks)

Question paper pattern for soft core 100 marks theory paper:

Each soft core theory paper is divided into 3 units. Each question paper will consists of

EIGHT questions of 20 marks each, drawn from all the three units. The student is required to

answer any FIVE questions out of eight. Thus the maximum marks for each question paper

will be (5 x 20 = 100 marks).

Each 20 marks question could be broken into 2 or 3 parts. Maximum marks for each part will

be 10 and minimum will be 4 marks. The student is required to answer all parts of the same

question.

Question paper pattern for open elective 100 marks theory paper:

Open elective theory paper syllabus is divided into 2 units. Question paper consists of 3 parts:

PART A, PART B and PART C. Part A consists of 3 questions of 20 marks each drawn from

Unit-1. The student has to answer any 2 out them. Part B consists of 3 questions of 20 marks

each drawn from Unit-2. The student has to answer any 2 out them. Part C consists of

consists of 6 questions of 5 marks each, 3 questions being drawn from each unit. The student

45

has to answer any 4 of them. Thus the maximum marks for the question paper will be

(2 x 20 = 40) + (2 x 20 = 40) + (4 x 5= 20) = 100 marks.

Each 20 marks question could be broken into two or three parts. The student is required to

answer all parts of the same question.

INTERNAL ASSESSMENT

There is NO internal assessment for soft core and open elective papers.

Internal Assessment for each hard core theory paper is for 30 marks. One internal test shall be

conducted for 25 marks in each paper. 5 marks are reserved for attendance.

Allotment of marks for attendance:

Attendance greater than 95 % - 5 marks

Attendance between 95 – 90 % - 4 marks

Attendance between 90 – 85 % - 3 marks

Attendance between 85 – 80 % - 2 marks

Attendance between 80 – 75 % - 1 marks

Attendance less than 75% - ineligible to appear for examination.

PRACTICAL EXAMINATION

Semester end practical examination for each practical course is for 100 marks. Internal

assessment for each practical course is for 30 marks. Marks for internal assessment shall be

awarded on the basis of the performance of the student throughout the practical course.

Internal test is NOT mandatory for this.
